Hi All,

I have a booking mailbox, let's say its email address is [email protected]. One of my users utilizes this booking mailbox and has scheduled numerous invites to external users. I have a requirement to change the booking mailbox's email address from [email protected] to [email protected]. Will there be any impact on the previously scheduled invites if I make this change?

Please guide me on how to change the booking mailbox email address from powershell, and let me know if it's possible to set [email protected] as a secondary email address.

    Hi, @Roger Roger

    When you change the primary email address of your booking mailbox, the previously scheduled invitation is usually still valid. These invitations are usually associated with the mailbox itself, rather than a specific email address. However, it is best to notify external users of this change to avoid any confusion.

    In Exchange on-premises, you can use the following command in Power Shell to modify the primary email address of a mailbox.

    Set-Mailbox -Identity "[email protected]" -PrimarySmtpAddress "[email protected]"

    You can then set up the secondary email address using the following command.

    Set-Mailbox -Identity "[email protected]" -EmailAddresses @{add="[email protected]"}

    In Exchange Online, you can manage the email address in the EAC.

    1.Select the mailbox you want to modify, and select "Manage email address types"

    User's image

    2.Select "Add email address type"

    User's image

    3.Enter the [email protected] and check "Set as primary email address", click Save and the old email address will automatically become a secondary email address.

    User's image

    When you change the email address, the previously schedule invites will not be affected because the mailbox is still same, only the email address changes.

    Follow the PowerShell commands to change the email address-

    1.       Connect to Exchange Online Connect-ExchangeOnline

    2.       Add the new Primary email address Set-Mailbox -Identity [email protected] -PrimarySmtpAddress [email protected] -EmailAddresses @{add="[email protected]"}

    3.       After this you can verify by running the command Get-Mailbox -Identity [email protected] | Select-Object PrimarySmtpAddress, EmailAddresses

    Let me know if you any query in above steps.
